随着常规能源的逐渐衰竭和环境污染的日益加重，对分布式发电系统的研究成为重要课题，而建立分布式发电系统的仿真模型成为研究的首要问题。文章介绍了一种基于分布式发电系统逆变器实验测试数据的反向建模理论—辨识建模，并推导了最小二乘法方程，建立了基于最小二乘法理论的matlab辨识系统，对并网逆变器功率输出响应进行辨识建模，以得到其传递函数。最后将由传递函数建立的简化模型与原模型比较，验证了系统辨识方法的可行性。

With the gradual exhaustion of conventional energy and increased environmental pollution , the research on distributed generation systems has become an important issue .Therefore,establishing model of distributed generation systems is the primary problem .In this paper , introducing a reverse modeling theory based on emulation ,which is sys-tem identification for building model , inverter model identification equations based on least squares method is presen -ted.In matlab system , identification based on the theory of least squares method is established .The transfer function is calculated by identifying on grid inverter power output response .Finally, a simplified model which is established by the transfer function is compared with the original model to verify the feasibility of system identification .
